It’s late, and the only light in Heeseung’s apartment is the glow from his dual monitors and the desk lamp by your side. You’re seated cross-legged on the couch, furiously scribbling equations into your notebook while he slouches in his gaming chair, slurping ramen and casually demolishing enemies in LoL.

“Baby,” he calls, not looking away from the screen, “why are you muttering? You’re distracting me.”

“I’m solving for x,” you reply without lifting your gaze. “And, excuse me, you’re the one clicking like a maniac.”

Heeseung chuckles, finishes his ramen, and saunters over. “Show me.”

You blink at him. “You want to see my math problem?”

He leans down, one arm propped against the back of the couch, his face dangerously close to yours. “I want to see what my genius girlfriend is working on.”

Flustered, you push the notebook toward him. “It’s just basic calculus.”

He hums, his eyes scanning the page. Then he grins. “Yeah, no idea what this means. But the way you talk about it?” He leans closer, his voice dropping. “So sexy.”

You shove his chest, your face burning. “It’s math, Heeseung!”

“Exactly.” Heeseung laughs, stealing a kiss. “My little nerd.”
